Y.,

a corporation of New York Application October 26,1956, Serial No.618,503 I 13 Claims. (Cl. 23S- 55) Y My invention relates to a'votingmachine of the general type illustrated in Shoup Patent No. 2,054,102 oflSeptember 15, 1936, which is in extensive use throughout the UnitedStates under the name Shoup Voting Machine.

Qne object -of the invention is to produce an improved votlng machine ofthe type set'forth.

v Voting machines of the type referred to are used for selectingintra-party candidates in primary elections and for electing inter-partycandidates in general elections.

In order to avoid the necessity of setting up one or more machines foreach political party participating in aprimary election, it hasheretofore been proposed to provide means whereby the voter himself, orthe election officer attending the machine, may instantaneously setthemachine according to the party aflliations of the voter desiring touse the machine. One such arrangement is disclosed in Shoup Patent No.2,251,254 or No. 2,251,255, both issued on July 29, 1941.

The voting machines disclosed in these patents were setand re-set foruse by successive voters of different political parties -by actuatingone or another of a number ofselector knobs each `of which served tolock all voting spmdles except those of the party with which the voterwishing to use the machine is ailiated.

Because the number of voting spindles which are to be temporarily lockedcan be large, and because, to lock these voting spindles, it wasnecessary to move certain parts from one position to another, andbecause of the weight 'and friction involved, the parts to be moved werecounterbalanced by a relatively strong spring without which it would bediicult, if not impossible, to move said parts. If, in such anarrangement of this type, the number of parts to be moved is large, thespring may be inadequate and resetting the machine requires much effort.If the number of parts is small, the spring will be too powerful and theparts were moved violently and with attendant shock. To use diferentsprings for different settings of the machine is not practical.

It fis therefore a still further object of the invention to produce animproved voting machine which can be re-set for use by successive votersof different parties, instantly and with very little exertion.

The Voting machines to be used are prepared according to the number ofpartiesand the number of candidates in the eld. This preparation is madeby, or under, the supervision of an ocial who is known as the custodian.When in use, the machines are under the supervision of an attendantknown `as the election officer.

It is necessary that the machine be protected against improper votingbetween the time the custodian has tinished preparing it, and thebeginning of the voting. It is also necessary that the election officer,and the watchers for the different parties, be able to see that all ofthe vote counters are set at zero before the first vote is cast and thatthe vote counters ble concealed before the rst vote is cast, and it isnecessary that the vote counters remain concealed until after the lastvote is cast.

' It has heretofore been proposed to lock the voting` machine in amanner which required the use of a key to unlock the machine to allowthe voting to begin. In the confusion that is often present and becauseof human frailty, the election oicer in charge of the machine may not beable to nd the key, or the key may not work, etc. with consequent delayand inconvenience.

j It is therefore a still further object of the invention to produce animproved voting machine which can be adequately locked againsttampering, but which can be placed in Voting position by the electionotlicer without the use of any key.

These and other objects are attained by my invention as set forth in thefollowing specification and as illustrated in the accompanying drawingsin which:

As best shown in Figs. 1, 19, 2O and 21, a voting machine includesvoting spindles S, which are operatively connected to vote counters Cand which are yactuated by The structure and operation of the votingspindles and the vote counters are disclosed in Pat. No. 2,054,102, aswell as in some of my other patents, and therefore are not shown nordescribed. Votview sectional view sectional sectional view sectionalview ing spindles S are provided with buttery ,cams B which,

view

eene-eee upon rotation of the voting spindles, in clockwise direction,as viewed in Fig. 20, engage and raise the corresponding voting spindlereturn members 10, as shown in broken'linesrin-Fig'. 20. When returnmembers 10 `move down to the solid -line position of Fig. 20,theyrrotate butterily cams B in :the opposite direction .and returnvoting spindles S to their ready to use position.- To control'theoperation `ofthe votingrspindles S, each voting spindle return memberis`pro`vided with 'a'rigidlyfconnected bottom bracket 14 which has arigidly `connected arm `16 whichcarries a'rigidly connected yroller 18.In the non-'voting position ofFig. 2l, roller 18 vrides on ltheat,slightly inclinedsurfa'cie u20 o'f Iac'am bar 22. VIn-this position,roller 18 cannot move downwardly land-filierefore return member l10-can'not -be raised 'and 'the -c'orrespending voting spindle' cannet beturned. 'fro enable the voter to'moveth'e voting spindle`return-member'-u'pwardlygcam bar .Z2-is provided 'With-'notches '24 andmeans is provided, for moving c'am `bar -22 in `va -dire'ction- 'tobring notches 24 .into registration -Withrollers-'18. 'In' Fig. 20, foneroller 18-is shown'fas it begins-to-move down into fa notch 24 'and'therefore -i`ts1-corresponding voting spindle Lretu'r'n member 10 may`begin'its upward movement by rota-tion of itis Corresponding butterflycam B. Whencam bar 22 `is -tnoved in the opposite'direction, verticaledge 25 of notch 24 engages-arm 18,-as shown in broken-'lines in Fig.-20, -and 'moves bracket 14, --aim 16 and roller 1S out of notch -24 andback-to the position 'oF-Fig. 2l in'vvhichretutnme'mbe'r 10 is -againJlocked against upward movement. The mechanism whichopensor-clos'estlie'voting machine curtain and which operates cam bar 22 willhereinafter be referred to. For -the pSnt-'iti's Si'lcie't T0 St'te thatCam bar V22 is 'IV- able, with the closing of the curtain, 'to theposition of Fig. 20, in which the voting spindles can be used, :and withthe opening of the-curtain'to the position of Fig. 2l in whichthevo'tin'g spindles lare locked.

In-o'rder fo-enable the custodian to lock the machine after hehasp'rep'ared-itand-until the shutters are lowered to permit the votingto begin, I provide a locking mechanism which includes an angle slidemember 30 and a lever 32'whichv is fulcrum'ed at 34 and the free end ofwhich engages ahole 36 in the horizontal wall of the slide as showninKFig. 1'2. Lever 32 is pivoted at 38 to the lower end 'of an arm 40,the upper end of which is pivoted at 42 to a link 4d Vwhich is pivotedat 46 to a handle 48. See Fig. -11i. By manipulating handle 48, slide 30may be moved to the right or to the left, as viewedinFig. l2.

In manual operation, movement of slide 30 to the right, as viewed inrFigQI'Z, 'disengage's :a p'a'wL'not shown, which normally engages aratchet, also not shown, on cam bar22,1so Vas 'to 'release the-cambarfor movement to the left with the closing of the curtain.'In'electrically operated machines,moveme'nt olf `slide 50' to thevright in Fig. il2 closes la-'nor'm'ally openiswitch, not'shown, whichenergizes motor M in a direction to close curtain 33. In'eith'er case,the vertical walls-of'slide Si) is provided with a hole 50 which, Iinthe llocked position Vof the machine is engaged by the end :52 of 'pin24 which is mountedfor movementthrough a hole in'a''xed portion 56'ofthe frame of the machine. vPin Seis biased'a'way from hole 50, or tothe right in Fig. 5, byra .spring'SS and'is provided'with an'enla'gedb`os's`60 which' is'adapted to.pass through notch-62 in main cambar 64which-is movable jointly with cam bar 22, in a manner and for a purposewhich form-no part of the present invention. It-issufcient to say that,when cam bar.22 is.in..its locked, or non-voting, position otFig. l.21,notch `62 .in cam bar 64 will register with boss-'60 and vice versa. Inother words,-in the locked position 4of the-machine, notch 62 in cam bar-64--andhole 50 1in :slide 130 will both bein registration with, andwill beengaged by, pin --54 and notches -24 incam bar 22 will be 4out ofregistration with roller 18 of voting spindle return niemi bers 10.Therefore, to release the machine for use, pin 54 must be disengagedfrom slide 30 and from cam bar 64. The manner in which this is done isshown in Figs. 7 and S and is hereinafter explained.

The machine is also provided with shutters 68 which are carried by plate70 kand which are movable to the lower position of Fig. 3, to cover vote-counters .C for to the -upper position of Fig. 4 to exposethefvote'counters. Shutters 68 are movably mounted Arelative to the-upper Wall 74 of a Z-shaped member (see Figs. 5 and .10), by means ofpins 76 which are carried by `plate 70-.and engage Cslanted slots 78 inwall l74. Plate 70 also-has slanted slots Si) through which pins 82carried by wall 74 pass t'obe engaged by Jcotter--pinsynot shown,movably to assemble the shutters to wall 74. By this arrangement, whenwail 74 is moved horizontally in one direction the shutters will moveupwardly and laterally in one direction and when wall 74-:is Vmoved.in-the.opposite-direction shutters 72 will move downwardly andlaterally inthe opposite direction.

In order .to control-.movement of wall 74, and, hence, themovement-ofthe shutters, intermediate wall86 of the Z-shaped memberreferred to is alsoprovidedwithteeth 88 which are selectively engageablewith the end 90'of dog 92 or Withthe end Y94 of dog'i96. Dogs 92 and 96are -freely rotatable on pins 98 which'project-from frame portionMandare-normally biasedin a direction to engage teeth-SS-byfsprings 99.Dogs 92 and 96`are'sele'ctivelydisengaged from :teeth 'Se byfimeansofIpinV 160 which iscarr-ied by .slide M2 whichismovable relative to wall74 o'f the-Z-shaped member to bringpin 100 .into position to depressthe'inner endtm of dog 912 or'theinner end 106 of dog v96todisengageione or the'other of said dogs from teeth 88. In Fig.9, 4dog-912 iis shown 'disengaged from, and dog 96 is shown enga-gedwith, teeth8S a'nd'there'fore, the--Z-shaped Vmembercanzbe 'moved to vthe `right as'viewed in Fig. 9. It is understood Jthat, if slide 102 is moved to` theright, -pin 106 will depress the end 166 of dog 96 and will disengageit-fromlteeth't so-that the Z-shaped member :may now-'be movedto theVleft as viewed in Fig. 9. Slide 102 is provided with a ratchet 112Which-'is adapted to-.beiengaged by a -pawl 11d-which is freelyrotatable on pin 116 which also projects from frame portion 56. Pawl1-14 is-'normally biased into engagement with the ratchet by spring 11S.-By-inspection ci Fig. 9, it will be seen that slide Vlil-'2 can -bemoved to theright as viewed irl-Fig. 5 regardless-oftheposition ofpawl'114, but'that slide`102-'cann'o`tbernoved to thelet inFigJ9 unlesspawl 1-'1'4`ha`s first been disengagedf'rom ratchet 112.

S1i`de102 maybe moved in eitherv direction, by means of a lock120`provided With'a cranlt'122'whi'ch is secured to the Vslide andfisadapted to be 'rotated by a key, not shown. Lock 12@ is conventional andis so 'constructed that' the -key may be inserted and removed only whenthe lock barrel is inagiven position and so'that the slightest turn'ofthe key in thelock` will'p'revent withdrawal of the key. This lockisknown as the'election 'oicers lock. Aspreviously stated, pawl 114, inthe position of `Fig. 9

prevents movement of'slide bar 102 to'the left While permitting movementoftheslide to the right of its position in Fig. 9, or to aposition inwhich end 940i dog 96 is'disen'ga'ged from teeth 8S. In order to be ableto move slide '102 to the deft, `or' back to the position of Fig. 9,Ipr'ovide 'anotherlock 124 whichiskn'own as the custodians lock. Thislock -is provided with a hoger 126 which, when lock 13.4 is turned inclockwise direction, asviewed in'Fig.' 9, willengagean extension 128 ofpawl 11:4 and'wilLlift thepawl outof engagement with ratchet 112. rThispermits movement of slide 162 to the left, or back to the position ofnFig-9 in which pin 190 will disengagedog 92 fromteethl 8S.

Inorder tolo-ck all-voting. spindlesexcept vthoseapertaining to theparty with which `the voter desiring tousc the Amachine is ailiated, YIprovide themechanismbest shown in Figs. 5, i3, 14 and l5. This machineincludes an vindex plate 140 which is provided with a number of stationswhich are marked R for Republican, D for Democratc, P for Progressiveand so on, 142 which is selectively movable to one or another of thesestations. If the voter is republican, handle 142 is moved to registerwith R, and if he is a democrat, the handle is moved to register with Dand so on. Handle 142 1s connected through suitable links and leverswhich are generally referred to by numeral 144 to arm 146 and thearrangement is such that, when handle 142 registers witl 1 R on indexplate 140, arm 146 is in its uppermost positron, or the position shownin Figs. 13 and 18, and viceversa. As will be seen from Fig. 12, arm 146is operatively connected at 148 to one arm 150 of a bell crank which ispivoted at 152 to a fixed frame portion 154 and the other arm 155 ofwhich is operatively connected at 156 toa serrated bar 158. By thisarrangement, when arm 146 is moved downwardly, serrated bar 158 willmove to the right as viewed in Fig. 12 and vice versa. Serrated bar 158is provided with a number of clips equal to the number of politicalp-arties in the eld, only two of these clips 160 and 162 being shown inFig. 14. As will be seen from Figs. 14 and 15, each of the clipsincludes a vertical wall 164 and a horizontal top wall 166 which has anopening 168 therein. Wall 164 of each clip is clamped onto the serratedbar 158 by a set screw or other means 169. By this arrangement, theclips can be arranged in any desired spaced relation along serrated bar158. Now, referring back to Figs. 15 and 20, it will be seen that theroller 18 of each voting spindle return member 10 is provided with afeeler formed of vertical wall 170 and a horizontal wall 172 which willoverhang top wall 166 of any clip 162 or 160 which is brought intoregistration therewith, as best shown in Figs. 14 and 15. It will berecalled that, for a voting spindle return member to move upwardly whena voting spindle is turned into vote counter actuating position, itscorresponding roller 18 must move downwardly into corresponding notch 24in cam bar 22. It therefore follows that, if a clip is so located on bar158 that the top wall 172 of the feeler referred to registers with thesolid portion of the top wall 166 of a clip, as in the position of clip162 in Fig. 14, the corresponding roller 14 cannot move downwardly andthe corresponding voting spindle return member cannot move upwardly andthe corresponding voting spindle will be locked out regardless of theposition of any, or of all, of the other parts of the machine. On theother hand, if a clip is so located on serrated bar 158 that top wall172 of its feeler registers with opening 168, in the top wall of theclip, as in the position of clip 160 in Fig. 14, the correspondingroller 18`l can move into corresponding notch 24 and the correspond--ing voting spindle return member can be moved upwardly and thecorresponding voting spindle can be moved in vote counter actuatingdirection. This is on the assumption that the other parts of the votingmachine are in votepermitting position.

In actual use, the custodian so arranges the clips on bar 158 that, whenhandle 142 is in position R, the clip or clips associated with thereturn members of the voting spindles assigned to the Republican partywill be in posi-- tions corresponding to the position of clip 160 inFig. 14- and the clips associated with the return members 10 of' all ofthe other voting spindles, will be in positions cor responding to theposition of clip 162 in Fig. 14. If handle 142 is moved to position D,the clips associated with thef Democratic party will assume positionscorresponding tothe position of clip 160 in Fig. 14 and so on.

In order to lock handle 142 against movement while the voting spindlesof the party indicated by the position.

of said handle .are being used, the lower end of arm 146v has a seriesof vertically spaced holes 176 and I provide cam bar 22 with a pin 178which, when cam bar is moved to the position of Fig. 12 will engage oneor another of holes 176. Pin 178 is spring loaded so that if, for anyreason. it is not in perfect alignment with one of holes-L and I providea pointer` 176, there will be no damage when cam bar 22 is moved to itsextreme lefthand position.

Intermediate wall 86 of the Z-shaped member is provided with teeth 180which are adapted to be engaged by a gear 182 the shank 184 of whichpasses through a slot 186 in the lower wall 188 of the Z-shaped member.In Fig. 8, the Z-shaped member is shown in its extreme righthandposition and, it will be understood that gear 182 can only be turned incounterclockwise direction to move the Z-shaped member to the left. Thebottom wall 188 of the Z-shaped member also has a slot 190 which isadapted to be engaged by the reduced proportion 192 of pin 54 and has anenlarged, round opening 196 which is adapted to be engaged by theportion of the body of the pin 54 which is to the right of the reducedportion 192 as viewed in Fig. 5. When the reduced portion 192 of pin 54is in slot 190, the Z-shaped member can be moved by rotation of gear 182to the left or to the right according to whether dog 92 or dog 96happens to be in engagement with teeth 88. When pin 54 engages enlargedopening 196, the Z- shaped member cannot be moved either directionregardless of the position of dogs 92 and 96. By inspection of Figs. 5and 6, it will be seen that reduced portion 192 of pin 54, can onlyengage slot 190 when the pin is pushed inwardly or to the left in Fig.5, against vthe action of spring 58. It will also be seen that pin 54cannot be pushed tothe left in Fig. 5 unless hole 50 in latch 30 is inregistration with the end 52 of the pin and unless notch 62 in main cambar 54 is in registration with boss of pin 54. On the other hand, whenenlarged opening 196 is in registration with pin 54, spring 58 will movepin 54 to the right in Fig. 5 to disengage boss 60 from notch 62 in maincam bar 64 and to disengage the end 52 of the pin from hole 50 in latch30.

In the drawings, the machine -is illustrated as the parts would appearat the end of the election, or after all of the voters have voted andwith the shutters 68 in their lower or vote counter covering position ofFig. 3. It is now necessary for the election oiicer and the watchers ofthe participating political parties to look at the counters .and recordthe totals for the various candidates. In order to raise the shutters soas to uncover the vote counters, the election officer puts his key inlock and turns it in clockwise direction to move slide 102 to the rightas viewed in Fig. 9. Movement of slide 102 to the right ldisengages dog96 from teeth 88, and permits movement of the Z-shaped member to theleft as viewed in Figs. 9 and 10. Movement of slots 78 in wall 74 of theZ-shaped member of the left relative to pins 76 causes the shutters tomove upwardly and -to the left as viewed in Figs. 3 and l0 to expose thevote counters as shown in Fig. 4. It will be noted that once theelection ohcer has turned his key in lock 120, he cannot take it outunless slide 102 is moved to the left in Fig. 9. But, because of theengagement of pawl 114 with ratchet 112, slide 102 cannot be moved t0the left and the election oicers key cannot be removed from the lock.

The machine is also provided with a normally open switch 200 and withcomb bar 202 which has spaced teeth 204 which are adapted to be engagedby rollers 18 of the voting spindle return members 10 when they movearcuately in notches 24. By this arrangement, if any return member israised, which takes place only if at least one voting spindle has beenturned to, and kept in, voting position, comb bar 202 will move to theleft as viewed in Figs. l2 and 16 and will close switch 206. On theother hand, if the voter turns no voting spindle, or, having turned itto voting position he turns it back, comb bar 202 will not be moved orwill be moved back to its inoperative position, as the case may be. Ineither case switch 206 will remain open. Switch 206 is in series withanother switch, not shown, which is inside the machine and which must beclosed to actuate motor M in a curtain opening direction. Therefore, ifswitch 206 is not closed, the curtain will not be opened and the voterwill -know that -he either didnot move any voting spindle or that heinadvertently moved them-backto non-voting position.

' At theend of `'the election, the custodian closes the doors'ofthemachine,not shown, and seals them. This is done in the presence ofthe various oiicers concerned and the machine is impounded for aprescribed period which varies from one jurisdiction to another. At ltheend of this period, the custodian breaks the seal and resets the votecounters to zero. 'He also puts -h'is lkey. in lock 124 and turns ittorelease--pawl r114 from ratchet 112. The election oicers key -maynowbeturned in counterclockwise direction, as viewed in Fig. 9 to -moveslidefbar 102 -to the left as viewed in this figure. The electionotlcers key can now be'removed -from the lockt'to bedelivered,together-'with the locked'and re-set machine, to the election voliicer`at the -next election.

When the machine isdelivered to the voting-place, cam -bar '22 willlbe-@in the 4position of Fig. 21 in which return members 141 fand,hence, the voting spindles, cannot Ybe moved, -latch 30will lbe-in-its'extreme left hand position of Figs. 12 and '23 in which normallyopen switch 31-remains openand curtain llcannot be closed; hole 50 inlatch itt-will be vengaged by end 52 of pin 54 and notchf62 in main ycamvbar 64 will be engaged by boss 61) onpin 54; shutters 63 will be -inthe upper, vote counter exposition ofFig. 4; dogs 92 and 96 will be inthe Aposition of Fig. V9;*slide 102 will Vbe in its extreme left handVposition of Fig. 9, the Z-shaped member `will be in its extreme'righthand positionof Figs. 6, 7 and 8; clips 160, 162,'etc. willbe'soa-rranged on rbar -158 that, when index 142 is in registration withR the clips associated with-voting spindles assigned cto lthe Republicanparty will occupy positions like the position of clip 160 land all otherclips will occupy positions similar to the posi tion of clip 162, andreduced portion 192 in slot 190 which, in turn means that end -52 of'pin54 cannot be disengaged from hole ll) lin latch 30 and boss 60 on pin 54cannot be disengaged-from notch 62 in main cam bar 64.

After having noted that all vote counters stand at zero, the electionoicer turns -gear 182 to the left as `viewed in Fig. v8 to nmove theZ-shaped member to the left as viewed in Figs. 7 and 8 to lower ltheshutters to the vote counter concealing position of Fig. 3. Thismovement of the Z-'shaped member brings large opening 196 intoregistration .with pin 54 which is now biased to the right, as viewed inFig. 5, to disengage the end 52 and boss 66 of the pin 'from holes StiYand :notch 64. This --releases latch -3'0 which may now be -rnoved tothe right `in Figs. l2 :and 23, to close switch 31, by manipulatinghandle 48 Vand releases main cam lbar 64 .whichmay now move to the left,jointly ywith cam bar 22, to bring thelatter to the position of Fig. 20.

In a general election, clips 16D, 162, etc. are either omitted 4ortheyare all arranged in positions similar to the position of clip 160mwhichnone of thegreturn members is Vlocked out. In y.a primary 1e leetion,;the,clips are so arranged that movement of index 142 to one positionor another brings selected clips, or groups of clips, into positionssimilar to the lposition of clip 160.

At the end ofthe election, the relection oicer puts his key in lock 120and turns it in clockwise direction to reverse the positions of dogs 92and 96 and Apermit movement of the Z-shaped members to the right, asviewed in Fig. 9 or in shutter raising direction. B ut, Vbecause pin5ft-.engages large opening 196, as in Fig. 7, the Z-shaped member cannotbe moved until pin 54 is pushed to the left in Fig. 5 to bring reducedportion .192 of pin 54 into slot 190. This, in. turn, cannot be doneunless latch 30 and main cambarofl are` in the locked position of themachine in whichthe lend 5 2 and boss 6,0 onpin 54 will enter hole 5 0and notch ,62 respectively. Once vthis is doneand ,thezfshapedmemberlismoved to move the shuttersto vote ,countenexposingposition, it cannot bev moved back because dog I90 will be in engagementwith teethiSS. Also, .because pawl 114 engages ratchet 112,

slide 102 cannot be movedl to the leftvn Fig. 9 `until thev` custodianoperates lock 124 to disengage pawl 114; the election oicer cannotremove his key.
